Description

Coupling tube

The invention relates to a coupling tube for flexible line connection of machine parts.

When assembling machines, machine parts that are mounted separately are often connected to one another via pipelines tied together. For example, a compressor is connected to a compressed air pipe with a compressed air tank tied together. Rigid pipe connections can usually not be used because a tight connection of the connecting pipe to the connecting flanges of the two machine parts an extremely exact one mutual spatial adjustment of the connecting flanges would make necessary. There are therefore flexible coupling tubes are used, which have a limited tolerance in the mutual distance and in the mutual lateral displacement of the machine parts to be connected can compensate. The flexible coupling tube, usually as a corrugated tube, especially as a tombac tube are trained are costly. Also can

The invention has for its object to provide an inexpensive coupling tube that has a flexible line connection of machine parts with great tolerance in the mutual arrangement of these Machine parts made possible.

This object is achieved according to the invention in a coupling tube of the type mentioned at the beginning by the \

Features of the characterizing part of claim 1. \

Advantageous embodiments of the invention are specified in the subclaims.

The coupling tube according to the invention consists of two Partial tubes that can be telescoped into one another. This means that the length of the coupling tube varies greatly possible to compensate for tolerances in the mutual distance between the machine parts to be connected. the both partial pipes are each connected to the machine parts to be connected by means of ball joints, whereby a mutual lateral offset of the machine parts can be compensated.

The coupling tube is inexpensive to manufacture because it consists of rigid tube parts and simple spherical bearing surfaces consists.

In the following, the invention is explained in more detail using an exemplary embodiment shown in the drawing explained. The only figure of the drawing shows a coupling tube half in axial section and half in side view.

The coupling tube consists of an inner part tube and an outer part tube 12, which telescopically inein ^ other are slidable, with a sealing ring 14 inserted into the inner wall of the outer part of the tube 12 the causes mutual sealing.

The ends of the two partial tubes 10 and 12 are each thickened and have an outer spherical bearing surface Mistake. The spherical bearing surfaces 16 of the partial tubes 10 and 12 are each in the manner of a ball joint a spherical ring-shaped bearing seat is used. The partial pipes 10 and 12 are thereby in a spatial The cone angle can be pivoted about the central axis of the bearing mount. The size of this spatial cone angle is essentially determined by the diameter of the spherical bearing surface 16 and the outer diameter of the partial tubes 10 and 12 determined.

The spherical ring-shaped bearing receptacles are formed by two ring disks 18 and 20. The two ring disks

ben 18 and 20 lie in the middle plane of the spherical finger surface to each other, which is the spherical outer bearing surface 16 records. Each ring disk 18 and 20 thus has approximately half the spherical ring surface of the outer bearing shell of the ball joint. A sealing ring 22 inserted into the bearing surface of the one annular disk 18 has the effect the sealing of the ball joint.

One in the contact surface of the washers 18 and 20 trained concentric step 24 causes an exact concentric joining of the annular disks 18 and 20. Bolts 26 penetrate the two ring disks 18 and 20 axially parallel and are with their thread ends protruding beyond the annular disk 18 in threaded holes in the mounting surfaces of the for Connecting machine parts screwed in. The screw bolts 26 thus simultaneously serve to hold them together of the annular disks 18 and 20 and for fastening the coupling tube to the machine parts to be connected.
